If only there was a way to express gigawatt-hours per hour in a simpler way.

Where do you see that mentioned? When I ctrl+f for 'hour' I only see "€900 a megawatt-hour" and "equivalent to about $1,850, a megawatt-hour", but no MWh/h or hour per hour or something.

    Ah! Right, yeah that unit is unfortunate. After moving into a place where electricity is metered for the first time (beyond student living places where you just pay a flat rate as part of the rent), I started looking into what devices use how much. The '-hour' unit is so confusing, also when converting ordinary Watts to whatever-hours, you need to use a conversion factor of 60×60=3600 to get anywhere. Not intuitive at all. Had we just used Joules (kJ and MJ mainly, where 1 Joule = using 1 Watt for 1 second), then by using a 1 kW device (e.g. microwave) for 100 seconds you can instantly tell that 100 kJ is the amount of energy used. On a yearly a bill of 9'000 MJ, you can instantly grasp the relative size of 100 kJ = 0.1 MJ, maybe you do this daily so 365×0.1 = 36.5 MJ. I am terrible at mental math but this much I can do. Alas. At least, that's how I think it all works, it's not like I ever got to practice this outside of Factorio (consumption/generation is all in Watts and storage in Joules).

      Much of a muchness - 1kw for 1 minute is 1 kilowatt-minute or 1/60th of a kilowatt-hour. It’s just a matter of perspective. The 60x60 multipliers are making it sound more complicated than it really is.

    Actually, this works in Safari with its new "Live Text" feature. https://www.apple.com/safari https://www.apple.com/safari I just confirmed that searching for "hour" will highlight that term in the image in addition to any regular text.[1] Though, I first had to click on the image, which is apparently what triggers the OCR; after that searching found the term even if I changed or released the input focus. This is my first time using this feature (your post reminded me that I had recently read about it), and my first time using Safari since I don't know when, so there may be more caveats to the behavior I'm not aware of. [1] I used the archive.ph version of the full article. Live Text didn't seem to work when viewing the image in isolation via your link above.

Like gigawatts? Probably expressed as an expected average, rather than peak (or both).
